A NURSE critically injured when his partner Gerry Edwards was stabbed to death may have made mistakes when telling police what happened, a court heard.

Chris Bevan answered questions at the Old Bailey today about the night an alleged intruder repeatedly stabbed him and Mr Edwards.

Paramedics pronounced Mr Edwards, 59, dead at the scene after he was stabbed at his home in Page Heath Villas, Bickley, on March 3.

David Kilcullen, aged 46, of The Avenue, Bickley, is accused of killing Mr Edwards and inflicting horrific injuries on Mr Bevan.

Kilcullen claims he was acting in self-defence after allegedly being sexually assaulted by the couple in their flat.

Earlier today the jury heard a video interview of Mr Bevan recorded in May.

In it the 57-year-old claimed that Kilcullen had visited the flat he shared with Mr Edwards on three or four different occasions.

Mr Bevan claimed Kilcullen had first become known to the couple after he accused Mr Edwards of looking at child pornography.

He was invited inside by Mr Edwards who wanted to prove his innocence.

The court heard how there were then other brief meetings between Mr Edwards and Kilcullen over the next year and a half.

On one occasion Mr Edwards apparently told his partner that Kilcullen had visited the flat with a woman before asking Mr Edwards to perform a sex act on him.

In his interview Mr Bevan said: “Of course Gerry was horrified. He said this girl was quite rough and common but I never saw her.

“Gerry was saying [Kilcullen] used to knock at the door and just walk in, which is probably what happened that night. That is probably why I didn’t hear anything until Gerry screamed.”

Following the recorded interview Mr Bevan then appeared via a video link from another room at the Old Bailey.

Paul Purnell, defending, said he doubted that Mr Bevan’s recollection of what happened that night was entirely accurate.

He questioned Mr Bevan’s claims that he and Mr Edwards had been lying on the floor of the couple's cramped kitchen during the attack when the walkway was just three feet wide.

Mr Purnell said: “I think your recollection is inaccurate when you say that you and Gerry were lying down. I suggest it would be difficult for two people to lie down in that space.”

He went on to claim that Mr Bevan and Mr Edwards were standing when they were stabbed and fought a running battle with Kilcullen in the kitchen, throwing kitchen utensils and attempting to grab him in “a bear hug”.

Mr Bevan denied the claim, adding: “It was not an error, he did ask us to lie down."

The court also heard how Mr Bevan was certain the knife came from his kitchen – contradicting the prosecution's argument that Kilcullen took the weapon with him from his bedsit on the night of the alleged attack.

Kilcullen denies murder and attempted murder.

The trial continues.
